I have had my Win 8 laptop for almost 9 years.
It’s been a fine computer and has done every thing I need.
But support ended for Win 8 and I purchased my first software that is not Win 8 supported !!
I have always resisted the free update to Win 8.1 just because I don’t like updates.
It’s cheaper at a few other places, $399-$410.
It’s got a lot of what I want/need.
8 Gig Ram (old 4 Gig)
4.1 Ghz processor (old 1.7)
256 Gig storage. This will be the first computer I have had with SSD.
Storage is not an issue as I keep most data on several externals.
3 USB ports Would really like more
Screen size is moot since this will be plugged into a “docking station”.
$400 bucks is in the budget if I cut a few other future purchases. I hear brakes are only a suggestion.
I love new computers because I like tweaking them, I also like the idea of a “clean” computer.
What I don’t like, is having to reinstall all of my software and setting all of my online accounts.
Bacon Time !!!!!! 
My laptop WIN 7 is till chugging along fine.
I had to get a new tower because the hard drive was getting clunky.
After trying to work with WIN 10- I went whole hawg into Linux Mint on the new desktop.
Win 10 ain’t too bad, but it’s no XP !!!!
My wife had a Win 7 laptop and for a couple of years, it was really clunky. There was nothing I could do to make it better. I ended up getting her a Chromebook.
I striped as much as I could from the Win 7 almost to factory settings and it runs like brand new now.
I have no idea what was there that was clogging it up.
